tain new and useful Improvements in Dye-' ing Apparatus, of which thefollowing is a specification.

My invention relates to improvements in dyeing-apparatus for use indyeing cops or packages of yarn and other textile materials. v

The object of my improvement is t0 s1mplify the structure andincrease'the efiiclency of the apparatus, and to render it moreconvenient and easy to operate.

The method and means for carrying out my improvements are fullydescribed in the following specification illustrated by theaccompanyingdrawings, in which like reference characters designate likeparts.

In the drawings: Figure 1 'is a vertical, sectional View of adyeing-vessel or keir showing the arrangement of the perforated tubes orstandpipes on which the yarnpackages are supported during the dyelngoperation; Fig. 2 is an enlarged, detail view of one of the standpipesshowing the method of assembling and compressing the yarnpackagesthereon; Fig. 3 is a detail view of the means for holding the packagesin-place on the standpipes; Fig. 4 is an enlarged elevation of thelifter-device for use in removing the packages from the standpipes; andFig. 5 is a plan View of the same.

Referring first to Fig. 1, A designates a cylindrical dyeing-vessel orkeir which is similar in general respects to that shown and described inUnited States Patent No- 1,052,817 granted to John C. Hebden andFrederick H. Daniell, Feb. 11, 1913. 'The keir A is closed by a suitablecover, not here shown, and has its interior divided into two andexhausted from the other in the manner well known and generally used inthis art. The two compartments A, A of the keir A are intercommunicatingthrough the medium of a series'of openings in the dia ,the same outsidediameter as the package Y phragmor false bottom a, and the dyeliquor isforced either one way or the other through these openings by the usualarrangeinent of a centrifugal pump connected with the pipes a, a

Daniell above referred to the means for supporting the yarn-packages ordye-cops in the keir consist of removable stringers adapted to besecured in the openings of the diaphragm or false bottom. In my presentimprovement I prefer to employ supports forated, with suitable openings6, 6, etc., for

the egress of the dye-liquor, to allow the rounding the pipe, and theupper end of the standp'ipe is closed by a plug or stopper 6' to preventescape of the liquor at this point, so

see Fig.2; In preparing the yarn or other material for the dyeing bath,according to the process.

for which-my new apparatus is designed, it is preferably wound onlongitudinally-contractible tubes to allow'for the axial compression ofthe packages. The simplest and preferred form of tube for use in thispractice consist of a helical coil of wire C, see Fig. 2, covered by aflexible sleeve 0 of reticulate'd fabric orany similar foraminousmaterial. The coil C serves to keep the sleeve 0 distended in tubularform to support the wound. cop in its original shape, while allowing itsendwise contraction, and the dyeingliquor or other fluid can. be readilyforced through the meshes of the sleeve to permeate the yarn-masssurrounding it.

Referring to Fig. 1, the yarn-cops or packages Y are asser'nbled on thestandpipes B in multiple and then subjected to end pressure to compressthe material and bring all portions of the am to a uniform density. Atthe bottom 0 each standpipe B is placed a loosely fitting flange D ofsubstantially and formed with a hubd which raises it slightly from theupper surface of the diaphragma. After the packages Y are all in placeon the standpipe B, a second flange D In the previous patent to Hebdenand latter to be forced into the yarn-mass suris placed against the endof the last package and by forcin it down on the pipe the whole mass ofyarn in the series of cops is brought under compression. This operationserves to press the individual packages Y tightly together at their endsto prevent escape of the liquor between them, and also acts to bring allparts of of the yarn mass to a uniform density so that the liquor willpermeate it more evenly. After the yarn has been compacted in this wayit is necessary to maintain it under compression during the dyeingprocess, and to accomplish this the upper flange D is secured inposition on the pipe B as next described.

In the patent before referred to the arrangement for compressing andholding the yarn-packages on their supports or stringers consistsessentially of means operated by screw-threaded nuts or levers adaptedto be screwed down against the end flange. It has been determined inpractice, however, that the yarn-cops can be compressed sufficiently byhand, without the use of mechanically operated means, and it is obviousthat this method is preferable since it requires much less time. That isto say, it has been found practical to force the cops down on theirsupports or standpipes to compact the yarn by hand-pressure alone, andtherefore the relatively slow operation of screwing down a hand-nut orwheel can be obviated. This results in a saving of considerable time inplacing and removing the large number of cops in the keir and increasesthe production of the finished material. It isalso desirable to effect aquick and easy method of holding the cops in place on the standpipesafter they have been compressed, and to provide for this I have devisedthe ingenious arrangement of fastening-means shown in Figs. 2 and 3.

Referring to Fig. 2, the standpipe B is preferably turned down slightlyat 6 near its upper end to adapt it to an accurate fit in the bore ofthe flange D, and extending through this reduced portion is a series oftransverse holes 6", b etc. The holes b may be of any suitable numberarranged at short distances apart and are adapted to receive thesecuring-means or lock-pin E for the flange D. The pin E is formed witha pointed projectile-like end 6 of slightly less diameter than that ofthe holes 6 and a head 6 of the same size as its end 0. The main body ofthe pin E is reduced in diameter throughout the greater portion of itslength, and this reduced portion 6 is made eccentric to the main axis ofthe pin,,see Fig. 3. The method of operating this means for holding theyarncops under compression on the standpipe B is as follows: Asufficient number of cops Y are placed on the standpipe to reach clearto its upper end. The flange D is then placed against the end of thelast cop and forced downwardly on the pipe the flange D.

until the cops are compressed as much as required. If desired, more copscan be added from time to time to increase the compression and renderthe mass still more dense. After the proper compression is arrived at,the lock-pin E is inserted through any one of the holes 5 according tothe position of When released by the operator the flange D will thenreact against the pin E and force, it into the position shown in Figs. 2and 3. This serves to carry the body e of the pin into engagement withthe side of the hole 6 in such manner that the end e and head 6 willprevent displacement of the pin until the pressure of the flange D isremoved. .In this way the flange D is held in position by the pin Eagainst the end of the package or cop Y and the pin, in turn, is held inplace in the hole 6 by the pressure of the flange. to remove the copsfrom the 'standpipes, after the dyeing operation is finished, it is onlynecessary to bear down on the flange D to release its pressure on thepin E and the latter can then be easily withdrawn from the hole 6 Forfacilitating the removal of the yarn? cops or packages from the keir Ihave devised a novel form of crate-like lifter F illustrated in Figs. 4and 5 of the drawings.

When it is desired This consists of the longitudinal rods or bars f, fpreferably three in number, connected together by the semicircularstrappieces f, f, etc. The lower ends of the; lon gitudinal members fare bent inwardly to provide the hook-like fingers or prongs F, f andthe upper ends are arched over and riveted together at f to form a sortof bail or handle. The straps f are riveted to the members 7 at anysuitable distance apart to reinforce and hold the structure together,and are adapted to partly encircle the cops Y when the prongs f arehooked under the lower flange D. Referring to Fig. 1, it will beobserved that the manner of cperating the lifter-device consists simplyin grasping it at the top and hooking the pron s f under the edge of theflange D, whi e carrying the members f into position alongside thecolumn of packages Y. The whole series of packages on one standpipe canthen be lifted out of the keir without necessitating the handling ofeach individual cop. By tilting the lifter to one side the packages canbe dumped into the box or other receptacle provided for them.

If desired a plurality of lifter-devices can be provided for eachapparatus in accordance with the number of standpipes arranged'withinthe keir. In this way a separate lifter-device is available for eachcolumn of yarn-cops, and when the latter are set in place on thestandpipes the lifters will remain standing in the keir, as shown inFig. 1, serving as a sort of cage or support for the cops and proiding-for lifting them out of the keir more expeditiously.

"That is to say, with a separate lifter-device provided for eachstandpipe considerable time will be saved in placing the cops within thekeir and in removing them therefrom, because several columns of theyarn-packages can be handled at a time, and, furthermore, no delay isoccasioned in replacing the lifter-device in position after removing oneset of cops.

It will be seen that the improvements above described serve as a simpleand convenient means for holding the cops under compression on thestandpipes in the keir and for removing them therefrom at the completionof the dyeing operation; and thus by proi'iding for greater facility inhandling the material a more economical operation and increasedproduction of the Whole apparatus is assured.

Various modifications might be made in the form and construction of theparts of my improved device without departing from the spirit or scopeof the invention;

Therefore, without limiting myself to the exact embodiment shown anddescribed, what I claim is 1. In a dyeing-apparatus, the combinationwith a perforated, tubular holder adapted to receive aplurality ofdye-cops or yarnpackages strung along its length, of a flange fitted toslide on the holder and adapted to be pressed against the end cop, and alocking-device for the flange consisting of a pin having its main bodyportion of less diameter than its ends and formed eccentric thereto,said pin adapted to be inserted through a transverse hole in the holderand to be locked thereinby the pressure of the flange against its side.

2. In a dyeing-apparatus, the combination with a perforated standpipeclosed at one end, of yarn-cops supported on longitudinally contractibletubes adapted to be strung on to the standpipe, an end flange forapplying pressure against the end package to compress all of thepackages, and a lock-pin for the flange adapted to be inserted through ahole in the standpipe, said pin formed with a laterally recessed bodyportion adapted to engage one side of the hole under the ac'- tion ofthe pressure of the flange to secure the pin in position in the hole.

3. In a dyeing-apparatus, the combination with a closed keir, of aplurality of perforated standpipes arranged vertically in the keir andadapted to receive the series of yarn-packages, flanges fitted to thestandpipes and adapted to abut the opposite ends of the series ofpackages, and a locking-device for holding the end flange in place onthe standpipe consisting of a pin formed with enlarged ends and a bodyportion of reduced diameter arranged eccentric to the main axis of thepin, said pin adapted to be inserted through a transverse hole in thestandpipe and to be locked therein by the pressure of the flange againstits side.

In testimony whereof I aflix my signature in presence of two witnesses.
